To synchronize video states inside of video zones in older versions of BrightSign presentations, and on players with older operating systems, you must send a Link Synchronize message in a leader zone and receive that message in an event that will listen for that message in follower zones. To do this:
...
Create the Leader Zone Message
Create a presentation with content inside of zones. Make sure to toggle on Interactive in the top right corner.
Select the transition event in the leader zone in your presentation. It may be helpful to include “Leader” and “Follower” in the zone names.
Add a transition event to the content you want to display first, then drag that event to the other content in the presentation.
In Event Properties > Advanced, select Add Command.
Select the Link command and the Synchronize command parameter.
Toggle the down arrow to enter a Keyword. This will be used to trigger follower players to display content.
Save the presentation.
